Public Function CaptureAsync (captureVisual As Visual, size As SizeInt32, pixelFormat As DirectXPixelFormat, alphaMode As DirectXAlphaMode, sdrBoost As Single) As IAsyncOperation(Of ICompositionSurface)

Parameters

captureVisual
Visual

The visual to capture.

size
SizeInt32

The size in pixels of the surface.

pixelFormat
DirectXPixelFormat

The pixel format of the surface.

alphaMode
DirectXAlphaMode

How the alpha channel should be handled.

sdrBoost
Single

float
